Title: Improvements in or relating to animal traps
IPC: A01M23/00
Filed: 1927-02-21
Abstract: 277,230. Trumbo, S. D. Feb. 21, 1927. Animal traps.-An upper frame 7 is provided with a marginal flange 6 that rests on projections in a lower receptacle 1. The horizontal part of the frame 7 is cut away to form two rectangular slots separated by a plate 9. Tilting platforms 12 are pivoted in bearings 10 at the ends of the slots and are provided with upper division plates 15 and lower vertical plates 13. A trip rod 22 secured to the supporting pivot of trip plates 17, a pair of which is situated at the end of each tilting platform, is adapted in the " set " position to engage in a slot 25 in an arc member 24 extending on the platform and so hold the platform from tilting. When an animal passes down the platform on to one of the trip plates in an endeavour to reach bait in a container 32 the trip plate tilts, freeing the rod 22 from the slot and permitting the platforms 12 to swing about their pivots and to precipitate the animal into the receptacle 1. Live bait may be contained in a supplementary container 33 the end walls of which are formed of wire mesh. The platforms are covered by detachable arcuate members 27 and bars 36 are fitted on the outside of the trap to facilitate animals reaching the entrance. A water tank 27 may be fitted within the receptacle 1 or water may be placed directly in the receptacle.

Title: Improvements in adjustable driving devices for the feed dog mechanisms of sewing machines
IPC: D05B27/22
Filed: 1959-02-12
Abstract: 849,795. Sewing machines. UNION SPECIAL MASCHINENFABRIK G.m.b.H.- Feb. 12, 1959 [Feb. 12, 1958], No. 4872/59. Class 112 In a sewing machine mechanism adapted both to vary the rate of feed and to reverse the direction of feed, a feed dog carrier is coupled by a connecting rod to an eccentric or crank on a driving shaft for receiving feed lift movement, while for receiving feed advance movement the carrier is coupled by a second connecting rod to a rocker arm oscillated at constant amplitude from said driving shaft, a pivotal connection between the second connecting rod and the rocker arm being displaceable on the latter along a path arcuate relatively to the pivot between the second connecting rod and the feed dog carrier, and said path extends on either side of a line passing through the pivot of the rocker arm and the pivot between the second connecting rod and the feed dog carrier. A feed dog 18 is fixed to one end of a feed bar 7 the other end of which is pivoted to a rocker arm 10<SP>1</SP> pivoted on a fixed shaft 10. A downward extension 12 from bar 7 is coupled by a connecting rod 11 to an eccentric 8 on a driving shaft 6 for receiving feed lift movement. A connecting rod 13 couples an eccentric 9 on shaft 6 to a rocker arm 14 on shaft 10. Arm 14 carries an arcuate slideway 15 in which is mounted a slide block 17 coupled by a connecting rod 16 to the extension 12. Slideway 15 is centered on the pivot between the members 12 and 16, and extends equal distances on both sides of the line joining said pivot and shaft 10. Displacement of block 17 above said line serves progressively to increase the rate of feed, and displacement downwardly to effect reverse feed of increasing magnitude. Block 17 is connected by a member 19 to a crank 21 on a shaft 22 which is biased by a spring to urge block 17 to the position of maximum forward feed. Shaft 22 is operably coupled to a shaft 34 which carries outside the machine frame a disc 25 provided with a lever 27 for rotating disc 25 over a fixed disc 26. A screw 28, threaded through disc 25, has an inner end 31 disposed within a prismatic notch 29 formed in disc 26. When end 31 engages the bottom of notch 29, block 17 is in the dead centre position of zero feed. When screw 28 is screwed outwardly, end 31 travels along one side of notch 29, under the influence of the spring acting on shaft 22, to set increasing rates of forward feed. At any position of end 31, disc 25 may be rotated to engage end 31 with the other side of notch 29 corresponding to reverse feed of equal magnitude. A pointer carried by disc 25 moves over a fixed, feed-rate indicating scale. A fixed stop 33 prevents rotation of disc 25 beyond the position corresponding to maximum feed. A crank on shaft 22 is connected to a treadle to providing an alternative means for altering the feed.

Title: Apparatus for testing ignition systems for internal combustion engines
IPC: F02P17/02
Filed: 1955-02-18
Abstract: 764,164. Testing ignition. NAPIER & SON, Ltd., D. Feb. 18, 1955 [March 30, 1954], No. 4982/55. Class 37. Apparatus for testing the ignition system of an internal combustion engine comprises an oscillograph having a cathode-ray tube connected to the ignition system so as to give indications representing the impulses delivered to the sparking-plugs, in which the time base is triggered by an impulse generated in a pick-up located near a cyclically-moving part of the engine which is adapted to produce a change of flux through the pick-up at a point in its movement approximately coinciding with a firing- point. An application is described to a sixcylinder four-stroke engine having magneto ignition. The vertical deflector plates are connected to the magneto primary, producing a trace on the screen as shown in Fig. 2. The pick-up is mounted near the fly-wheel, which has a projection on or a hole near its periphery, to provide triggering impulses for the time-base. These impulses occur once every crank-shaft revolution (Fig. 3), whereas the firing cycle occurs once every two revolutions. The impulses from the pick-up 13 (Fig. 4) are therefore fed, perhaps through an amplifier 37, to the grid of a triode 29, the anode voltage of which is supplied from the magneto primary. The triggering impulse is derived through a transformer 32. It will be seen from Figs. 2 and 3; that the triode anode has a positive voltage and negative voltage at each alternate impulse, whereby the triode transmits every alternate impulse to the time-base. This triode can be omitted for a two-stroke system. In the case of a coil ignition system, or a magneto ignition system with an even number of firing points per crank-shaft revolution, the pick-up may be mounted near a member moving at cam-shaft speed. The pick-up may be positioned at the crank-shaft top dead centre position, in which case, to allow for considerable spark advance, a condenser 36 is included in the triode anode circuit, to prolong the period for which the anode is positive. Instead of a triode, a polarity sensitive electromagnetic relay can be used, its contacts being closed when the magneto primary voltage is positive. Alternatively, a thermionic valve with two grids may be used, the pick-up impulse being applied to one grid, and the magneto primary to the other, the anode being constantly positive. Specifications 563,502, 606,739 and 608,324, [Group XXXV], are referred to.
